The Benefits of Vibrations

20.03.2017

Scientists from Augusta University, USA conducted an analysis of the results of using a less common type of body exercise - "vibration of the whole body" (BVT). It turned out that in mice, bones and muscles react in much the same way as regular exercise. This observation can be useful to quite a few who cannot go to the gym.

Such vibration looks like this: a person sits, stands or lies on a machine with a vibrating platform, and when it vibrates, it transfers energy to the body, so that the muscles contract and relax several times per second.

The researchers took two groups of male mice, five weeks old. They put normal mice in one group, and genetically modified mice in the other so as not to respond to the hormone leptin (which contributes to the feeling of fullness after eating). Mice from both groups were subjected to different exercises.

After a week had passed, as the mice became accustomed to the equipment, both groups began a 12-week exercise program. Mice in the IWT group "worked out" for 20 minutes a day, vibrating at a frequency of 32 Hz, with an acceleration of 0.5g. In another group, the mice walked on a slightly incline treadmill for 45 minutes a day. Finally, mice in the control group were not exercised at all. all mice were weighed monthly.

Mice genetically destined to be obese received similar metabolic benefits from the treadmill and IWT, and gained less weight than mice not exercising at all, although they remained heavier than normal and exercised mice. In addition, both types of exercise increased muscle mass and insulin sensitivity in genetically engineered mice.

All this together leads to the conclusion that therapy with IWT can be very useful for people with morbid obesity. And in general, many find it difficult, for various reasons, to exercise regularly, which only contributes to the spread of obesity and diabetes, which, in turn, weaken the bones.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Vaccine against disinformation 26.08.2022

A team of psychologists from the Universities of Cambridge and Bristol created 90-second videos to explain to users online manipulation techniques such as scapegoating and deliberate incoherence.

The scientific study consists of seven experiments involving almost 30 people and shows that even just one viewing of an instructional video increases awareness of misinformation.

There were 6464 participants in the six initial experiments (the sixth was conducted a year after the first five to allow past results to be tested). Participant data collection was comprehensive, from basic information - gender, age, education, political affiliations - to conspiracy thinking, news and social media checks, and more.

Lead author Dr John Ruzenbeek of SDML Cambridge explains: "The effect of the inoculation was the same for liberals and conservatives. It worked for people with different levels of education and different personality types. It's such a general educational inoculation against misinformation."

"Malicious disinformation takes many forms, but manipulative tactics and narratives are often repeated and therefore predictable," says Beth Goldberg, co-author and head of research and development at Google Jigsaw. "We've shown that a pre-emptive video clip can reach millions of people online, possibly before malicious narratives take root in their minds."
